Air Handler Features and Benefi ts Air Coil

Designed for R-410A refrigerant. Configured as an 'A' coil,

aluminum tubes and enhanced corrugated lanced aluminum

fins to provide high efficiencies at low face velocities.

Cabinet

Constructed of heavy gauge environmentally-responsible

galvanized steel for maximum corrosion resistance. All

units are painted with a powder coat finish. All interior

surfaces are lined with 1˝ thick, foil lined acoustic type

fiber insulation, applied in a manner that prevents the

introduction of glass fibers into the air stream. Multiple

knockouts in various sizes facilitate power and low voltage

wiring. Multiple access panels for ease of service.

Factory SealedAchieves 2% or less total airflow leakage rate.

Installation EaseCabinets are shipped in one piece but can be separated for

ease of installation in tight spaces.

Auxiliary/ Emergency Electric Heat

Electric heat packages can be factory or field installed.

For field installed electric heat the Auxiliary Heat

Compatibility table below shows the available heater

packages for the air handler.

ConfigurationsCabinets are factory configured for upflow and horizontal

right hand air discharge installation but can be easily

configured for horizontal left hand or bottomflow air

discharge.

Drain Pans

Two composite drain pans included. One for vertical and

one for horizontal applications. The pans come equipped

with primary and secondary drain connections.

Electrical DisconnectFactory installed circuit breaker on 15kW/20kW heaters.

Expansion Device

Factory installed TXV with internal check valve inside

of cabinet.

Refrigerant Connections

Suction and liquid lines have sweat connections extended

outside of cabinet for ease of connection.

Controls

The SAH Air Handler has two control options.

Control option 'A' has a terminal strip board that uses the

24V input from the thermostat to control the 5 speed ECM

motor.

Control option 'C' has the AHB board. The AHB is part of

the Aurora controls platform and communicates via modbus

to the ABC. The AHB board controls the air handlers

variable speed motor, auxiliary heat staging, provides

condensate overflow protection, air coil freeze protection

FP2, auxiliary heat and blower energy monitoring, leaving

air temperature, and is Symphony compatible with Aurora

controls in the compressor section..

5-Speed ECM Constant Torque MotorsThe 5-Speed ECM is a 'Constant Torque' ECM motor and

delivers air flow similar to a PSC but operates as efficiently

as an ECM Motor. Because it's an ECM Motor, the 5-Speed

ECM can ramp slowly up to down like the ECM motor. There

are 5 possible speed taps available on the 5-Speed ECM

motor with #1 being the lowest airflow and #5 being the

highest airflow. These speed selections are preset at the

time of manufacture and are easily changed in the field if

necessary.

If more than one tap are energized at the same time, built

in logic gives precedence to the highest tap number and

allows air flow to change with G, Y1, Y2 and W signals. Each

of those 5 speeds has a specific 'Torque' value programmed

into the motor for each speed selection. As static pressure

increases, airflow decreases resulting in less torque on the

rotor. The motor responds only to changes in torque and

adjusts its speed accordingly.

The 5-Speed ECM motor is powered by line voltage but the

motor speed is energized by 24 VAC.

5-Speed ECM Benefits:

• High Efficiency

• Soft Start

• 5 speeds with up to 4 speeds on-line

• Built-in logic allows air flow to change with G, Y1, Y2

and W signals

• Super efficient low airflow continuous blower setting.

Setting Blower Speed - 5-Speed ECM5-Speed ECM blower motors have five (5) speeds of which

three (3) are selectable on single speed and four (4) are

selectable on dual capacity.

Caution: Disconnect all power before performing this operation.

SAH Control Option C AHB Board The SAH Air Handler with the 'Advanced' control option

expands on the capability of the Aurora 'Advanced' Control

(ABC and AXB) in the compressor section, by adding the

AHB board in the air handler.

NOTE: The Energy Monitoring and Leaving Air Temperature features at the AHB board are dependent on the AXB board in the compressor section.

It is highly recommended that the installing/servicing

contractor use an Aurora Interface and Diagnosic Tool

(AID) when installing and servicing an Aurora 'Advanced'

control system.

The AHB board includes the following features:

AHB DIP Switch

DIP 1 - ID: This is the AHB ModBus ID and should always

read Off.

DIP 2 & 3 - Future UseDIP 4 & 5 - Accessory Relay2: A second, DIP configurable,

accessory relay is provided that can be cycled with the

compressor 1 or 2 , blower, or the Dehumidifier (DH)

input. This is to complement the Accessory 1 Relay on

the ABC board.

Position DIP 4 DIP 5 Description

1 ON ON Cycles with Fan or ECM (or G)

2 OFF ONCycles with CC1 first stage of compressor

or compressor spd 1-6

3 ON OFFCycles with CC2 second stage of

compressor or compressor spd 7-12

4 OFF OFF Cycles with DH input from ABC board

IntelliZone2 Zoning Compatibility (Optional IntelliZone2 Communicating Zoning)

A dedicated input to connect and communicate with the

IntelliZone2 (IZ2) zoning system is provided on P7 on the

AHB and AXB. This is a dedicated communication port using

a proprietary ModBus protocol. An AXB in the compressor

section or an AHB in the air handler is required. Consult the

Intellizone2 literature for more information.

Communicating Digital ThermostatsThe Aurora controls system also features either mono-chromatic or color touch screen graphic display thermostats for user interface. These displays not only feature easy to use graphical interface but display alerts and faults in plain English. Many of the features discussed here may not be applicable without these thermostats.

Energy Monitoring (AXB Board Required in Compressor Section)(Standard Sensor Kit on ‘Advanced’ models)The Energy Monitoring Kit includes two current transducers (blower and electric heat) so that the complete power usage of the air handler can be measured. The AID Tool provides configuration detail for the type of blower motor, power adjustment and a line voltage calibration procedure to improve the accuracy. The information can be displayed on the AID Tool or selected communicating thermostats. The TPCM32U03A(*)/04A(*) will display instantaneous energy use while the color touchscreen TPCC32U01(*) will in addition display a 13 month history in graph form. Refer to Compressor Section Start Up Energy Monitoring for configuration details.

Freeze Detection (Air Coil) – uses the FP2 input to protect against ice formation on the air coil. The FP2 input will operate exactly like FP1 except that the set point is 30 degrees and is not field adjustable.

Condensate Overflow – fault is recognized when the impedance between this line and 24 VAC common or chassis ground drops below 100K ohms for 30 seconds continuously.

Leaving Air Temperature (AXB Board Required in Compressor Section)A leaving air temperature (LAT) thermistor is located near the blower inlet and can be read via the AID tool or AWL.

Electric Heat StagingThe AHB board provides two stages of auxiliary heat operation. During normal operation, the first stage of electric heat is energized 10 seconds after the W command is received. If the demand continues the second stage is of electric heat will be energized after 5 minutes. In an Emergency heat operation the time delay between stage one and stage two will be 2 minutes.

Setting Blower Speed - Variable Speed ECM The ABC board’s Yellow Config LED will flash the current

ECM blower speed selections for “G”, low, and high

continuously with a short pause in between. The speeds

can also be confirmed with the AID Tool under the Setup/

ECM Setup screen. The Aux will not be flashed but can be

viewed in the AID Tool. The ECM blower motor speeds can

be field adjusted with or without using an AID Tool.

ECM Setup without an AID Tool

The blower speeds for “G”, Low (Y1), High (Y2), and Aux

can be adjusted directly at the Aurora ABC board which

utilizes the push button (SW1) on the ABC board. This

procedure is outlined in the ECM Configuration Mode

portion of the Aurora ‘Base’ Control System section. The

Aux cannot be set manually without an AID Tool.

ECM Setup with an AID Tool

A much easier method utilizes the AID Tool to change

the airflow using the procedure below. First navigate to

the Setup screen and then select ECM Setup. This screen

displays the current ECM settings. It allows the technician

to enter the setup screens to change the ECM settings.

Change the highlighted item using the ◀ and ▶ buttons and

then press the ◙ button to select the item.

Selecting YES will enter ECM

speed setup, while selecting NO

2 – Use manufacturer’s part number 19P592-01 (jumper bar assembly) when single source power is required.3 – Low voltage wiring CLASS 2.4 – DIP switch 1 on SW1 must be set in the OFF position.


If two separate circuits are used to supply power to the auxiliary heat kit, the Installer will need to verify that each leg of the auxiliary heat circuit breakers are wired from the power supply correctly in order for the electric heat kit to operate properly. This can be done by measuring the supply side voltage of the auxiliary heat circuit breakers. Put a voltmeter on the L2 side of Circuit Breaker One and on the L2 side of Circuit Breaker Two. The voltmeter should read approximately 0 volts. If the meter reads high voltage, the auxiliary heat breakers need to be rewired so that breakers in the auxiliary heat kit match the wiring of the Disconnect Panel breakers. Meaning, L1 and L2 from one breaker in the disconnect panel must connect to L1 and L2 at one of the auxiliary heat circuit breakers and L1 and L2 from the other breaker in the disconnect panel must connect to L1 and L2 of the other auxiliary heat circuit breaker, making sure that the L1 and L2 from each disconnect breaker matches the L1 and L2 at each of the auxiliary heat breakers.

AIR HANDLER2-6 Tons

SAH


Engineering Guide Specifi cationsGeneral

The air handler shall provide vertical upflow, downflow, or

horizontal configurations in one package. Units shall be

listed by a nationally recognized safety-testing laboratory

or agency, such as Underwriter’s Laboratory (UL) or

Environmental Testing Laboratories (Intertek-ETL). The

air handler units shall be designed and AHRI performance

listed to operate with the geothermal split condensing units

as provided by the manufacturer. Each unit shall be pallet

mounted and shipped using dense cardboard corners/top

and stretch wrap for easy shipping damage inspection.

Casing and Cabinet The cabinet shall be fabricated from heavy-gauge

galvanized steel and polyester powder coat paint to

withstand 1000 hours of salt spray testing. The interior

shall be insulated with 1 in. thick, multi-density, cleanable

aluminum foil coated glass fiber with edges sealed or

tucked under flanges to prevent the introduction of glass

fibers into the discharge air. One large blower compartment

access panel shall be provided and shall be removable

with supply and return ductwork in place. The internal

components layout shall provide for major service with

the unit in-place for restricted access installations. The

blower assembly access shall be slide-out serviceable via a

‘works-in-a-drawer’ design. The cabinet shall be convertible

to horizontal or downflow applications by reconfiguring

the cabinet using only a nut driver. The unit shall be ‘zero

clearance’ approved on any of its external surfaces.

Refrigeration Circuit All units shall provide a fin tube air-to-refrigerant heat

exchanger of the “A” coil design. The finned tube coil shall

be sized for low-face velocity and constructed of lanced

aluminum fins bonded to aluminum tubes in a staggered

pattern. The coil shall include a composite drain pan.

The thermal expansion valve shall be factory installed and

provide proper superheat over the entire liquid temperature

range with minimal “hunting.” The valve shall operate in the

cooling mode through the use of an internal check valve.

Blower Motor and AssemblyThe blower shall be an oversized direct drive centrifugal

type with a dynamically balanced wheel. The housing

and wheel shall be designed for quiet low outlet velocity

operation and of galvanized or galvalume steel construction.

Tight blower housing geometry shall not be permitted. The

blower housing shall be removable from the unit without

disconnecting the supply air ductwork for servicing of the

blower motor through a ‘works-in-a-drawer’ design. The

high efficiency blower motor shall be either a 5 speed ECM

or a variable speed ECM type. The blower motor shall be

isolated from the housing by rubber grommets. The motor

shall be permanently lubricated ball bearings and have

thermal overload protection.

Electrical A control section shall be located within the air handler

compartment and shall contain either a 75VA or 100VA

transformer, 24 volt activated. Transformers shall be

protected by internal circuit breakers. Units shall be

name-plated for use with time delay fuses or HACR circuit

breakers. Unit controls shall be either communicating

or 24 volt type. An Aurora AHB (control option C), a

microprocessor-based controller interfaces with the ABC

located in the compressor section to control unit operation,

shall be optional. The AHB control shall provide operational

sequencing, blower speed control, air coil freeze detection,

condensate overflow sensing, auxiliary heat staging, field

selectable options, and accessory output.

An integral circuit breaker shall be provided on all units

employing 15 kW or 20 kW electric heat. The control

shall maintain the blower operation 30 seconds after the

compressor or electric heat inputs have terminated.

A terminal block with screw terminals will be provided

for field control wiring. All units shall have knockouts for

entrance of low and line voltage wiring. The blower motor

and control box shall be harness plug wired for easy

removal.

An optional Aurora Interface Diagnostic (AID) Tool shall

communicate with the Aurora control allowing quick and

easy access to setup, monitoring, and troubleshooting of

any Aurora control. The device shall include the features of

fault description and history, manual operation capability,

sensor readings, timings, and other diagnostic tools.

Piping Refrigerant connections shall be made using sweat

copper joints. The condensate connections shall be a 3/4 in.

NPT.
